which seem never to have heen described, may now be given. 

 Corolla smooth and (in a dried state) purplish-blue, 6 lines long; 

 tube very slender, limb of 4 linear-oblong lobes, spreading or 

 moderately reflexed : stamens and pistil conspicuously exserted, 

 anthers blue, curved, versatile. — On dry talus of cliffs in shade, 

 barranca near Guadalajara, September, 1891 (n. 3852). The elon- 

 gated corolla fully confirms Dr. Watson's view that this is a 

 Crusea, and not a Spermacoce. 



Valeriana albonebvata. Tuber two inches in diameter: stem 

 erect, two feet in height, sulcate-striate, pubescent, subsimple up 

 to the branched inflorescence, nearly leafless : radical leaves numer- 

 ous, pinnate; leaflets 3-4 pairs and an odd one, broadly obovate 

 or suborbicular in outline, sometimes an inch in diameter, mostly 

 smaller, cuneate at the base; limb more or less divided into 3-5 

 broad rounded lobes ; the edges and veins beneath covered with a 

 short and dense white pubescence: petioles pubescent, 2-4 inches 

 long; cauline leaves 1-2 pairs, distant, much reduced; inflores- 

 cence regularly dichotomous; bracts awl-shaped, 1-1 jj lines long-, 

 flowers small; corolla a line wide, scarcely half as long: stamens 

 exserted: fruit ovate, glabrous, 2 lines long, crowned by the 

 spreading plumose calyx-teeth of the same length. — Hillsides, 

 San Jose" Pass, San Luis Potosi, July, 1890 (n. 3612), 



Eupatorium filicaule, Schultz Bipontinus. Stem slender, 

 terete, striate, the upper part covered with a very short close pu- 

 bescence: leaves opposite, membranaceous, petiolate, ovate, sharply 

 acuminate, subcordate or somewhat hastate, serrate, nearly or 

 quite glabrous on both surfaces, 2 inches long, 1| inches wide: 

 petioles flexuous, pubescent, 9 lines or more in length ; inflores- 

 cence of slender opposite spreading branches, bearing numerous 

 sub-racemose heads; pedicels filiform, 1-1£ lines long, fasciculately 

 grouped upon the branches: bracts filiform, heads 2-§- lines long: 

 scales of the involucre 9-12, linear-oblong, sharply acuminate, the 

 two or three outermost much shorter than the others, all thin, 

 striate, tending to turn purple, minutely pulverulent-pubescent: 

 achenes somewhat clavate, puberulent at the angles, narrowed be- 

 low into a sort of stipe. — Near E. Palmeri, Gray, but differing in 

 its more delicate foliage, more racemose heads, and in the achenes 

 attenuated downward. This and the following seem to be good 

 species, which were named by Schultz Bipontinus, but, so far as I 

 have yet been able to learn, were never described. The description 

 above is drawn, not from the type which is Ehrenberg's no, 1176
